IMPROVEMENT IN CO MBINED REEL AND RAKE FOR HARYES'IERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, SAMUEL H. BINGMAN, of Laurelton, in the county of Union, and State of Pennsylvania, have invented an improved Self-Acting Reel and Bake for Harvesters; aml I do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawings making part of this specification.

Figure 1 is a plan of a harvester platform, together with my improved reel and rake and the working parts connected therewith.

Figure 2, a front elevation of the same.

Figure 3, a similar elevation, the housing being removed to show the working parts more completely.

, Figure 4, a view of the under side ofa reel or rakehead.

Like letters designate corresponding parts in all of the figures.

Letter A represents a harvester platform.

Near the front inner corner thereot'is mounted a vertical shaft, B, upon or around which operate the reel or reels 0 D, (one, two, or more,) and the rake (.lr.

Each reel as well as the head of the rake being of sufiicient length to reach across the harvester platform,

is provided with a central slot, a, extending nearly its whole length, and of uniform width, just sufiicient to embrace the shaft B. Around the entire outer edge or periphery thereof, which is semicircularat the two ends, is a rack, I), which gears into a pinion on a vertical driving shaft, H, situated at the proper distance from the shaft B.

Each reel and rake, O, I), and G, respectively, has

a pinion, c, d, and g, on the said driving shaft, the sit-t nation of'which is laterally opposite to the shalt B, so that, on communicating the proper motion to the driving shaft in any suitable way from the driving wheels of the harvester, the motionof the reels and rake will be first directly and longitui'linally forward their whole length into the standing grain, while the pinions are in gear with the side racks thereof, and then they will make a quick sweep backward over the harvester platform, through a half circle, when the plnions reach the semicircular end racks thereof, the reels .bringinglthe standing grain back over the platform, while the rake, which is below the reels, sweeps the cut grain from the said platform. Then the other end of each reel and rake goes forward, repeating the movement.

' The reels are so arranged, if there are only two, as to alternate in action, one, as G, fig. 1, being half. way

in its forward movement, while the other, as D, fig. 1, is in the middle of its semicircular turning movement. The pinion g, which drives the rake G,'is loose on the driving shaft H, and a clutch, I, is provided, so that, by depressing a lever, -13, it will engage with the pinion, and couple the same to the shaft.

Thus, after each movement of the rake, its pinion, g, is uncoupled, and does not turn with the dritving shaft, so that the rake remains stationary till enough cut grain has accumulated on the platform to form a gavel, when the leveri is depressed by the driver, and

1 by coupling the pinion g to the driving shaft, the rake is given a movement tosweep the gavel from the platform. 1

The rake-teeth h h are suspended by semi-cylindrical heads I l, reaching transversely across the rake head, and resting in sockets of similar form in a supporting bar, 112, suspended with a slight play from. the rakehead. p

The design'of the construction is to have the bar in pressed, by suitable means, upward to the rake-head, so as to hold the rake-teeth rigid while the rake is in operation; but to let the bar down so as to leave the teeth to yield to obstruct-ions when the rake is stationary on the machine, any convenient and suitable means may be employed for giving alternate rigidityand looseness to the rake-teeth, as required.

The reels and rake are supported upon and between proper washers and shoulders, 11111), on the shaft B, to hold them at the right height and in horizontal posisitions at all times. r Y

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. The reels G D and rake G, having central oblong slots a, a c to embrace a guide-shaft, B, and continuous edge racks l) b b which gear into pinious 0, (Z,- and g on adriving shaft, H, so as to operate substantially 1 as and for the purpose herein specified.

2. In combination with the rake G, constructed and operating .as described, the clutch I, as and for the purpose set forth.

3. The combination and arrangement of the reels 0 D, rake G, shaft 15, piuious c d 9, driving shaft H, and clutch I, substantially as herein set forth.
